Rank the following compounds in order of their solubility in water

CH3OH
HOCH2CH2OCH2CH2OH
CH3CH2CH2CH3
(CH3)2CHOH

I can't get this question right! please help :)

CH3OH > HOCH2CH2OCH2CH2OH > (CH3)2CHOH > CH3CH2CH2CH3
All of the first three are completely miscible in water so the ranking may be arbitrary and any alcohol could be first, second or third.
